Use the methods introduced in rL356276 to implement the computeOverflowForUnsigned(Add|Sub) functions in ValueTracking, by converting the KnownBits into a ConstantRange. This is NFC: The existing KnownBits based implementation uses the same logic as the the ConstantRange based one. This is not the case for the signed equivalents, so I'm only changing unsigned here. This is in preparation for D59386, which will also intersect the computeConstantRange() result into the range determined from KnownBits. llvm-svn: 356290 |
